After someone tried a buffer overflow attack I started getting a message from cron like this:

/etc/cron.daily/00webalizer:

Error: Skipping oversized log record

Webalizer.conf says that the logfile is /var/log/httpd/access_log but I look at that file and it's empty. This must be why there's nothing when I look at the Apache Access Log in the System Logs GUI. Access_log.1 has the buffer overflow attack with other items after it. Why am I getting this message and why has it stopped logging?
